Dr. Judy St. Leger will headline this year’s MACNA Banquet as the Keynote Speaker. The founder and president of Rising Tide Conservation, Dr. Judy St. Leger is an aquatic animal veterinarian committed to ocean conservation. Back in 2009, her boss wanted a new way to approach reef conservation that would provide alternatives to fish collections. From this idea, Rising Tide was born. Leger’s presentation is titled Aquaculture and Sustainability: No more clowning around.
